This activity was created for middle or high school math stations on square roots and irrational numbers. It can be used for three different activities: comparing, ordering, and operations. Number cards, spinners, number line, and activity sheets are included. I like to just use paper clips as the spinners, but you can use the arrows that are included. It will give your students the opportunity to each complete a unique set of problems. They spin the spinners to choose the symbol and then pick two cards to choose the numbers to use. I laminate the included student directions to keep at the station.

CCSS.Math.Content.8.NS.A.2 Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (e.g., π2). For example, by truncating the decimal expansion of √2, show that √2 is between 1 and 2, then between 1.4 and 1.5, and explain how to continue on to get better approximations.
